Well, for one thing, don't hide out in your bedroom if you don't want it to look like her being there bothers you. Just go about your business like you normally would (unless that is to prance around naked).

My SD was a good kid, but not wanting kids, it was still hard for me sometimes, so I get where you're coming from. But if I wanted to sit in my living room watching TV all weekend, that's what I did. I did not let her presence dictate my life.

The less you change your routine when she's there, the less her being there will bother you.

Don't get me wrong, I still let out a sigh of relief when DH took her home, so it's not the perfect solution but it helped!

I used to hide out when my SS's were here too. Then I got fed up with it and took back control of my home. I realized that once I stopped hiding, they started. They would stay in their rooms the whole time. Eventually they just stopped coming. I didn't do anything to make them feel they had to stay away from me, I just didn't let them run the house. BM lets them control her house.

Go to an afternoon movie alone! Ride your bike, go for a loooong walk. (I'm all about getting out of the house).
